Cool. I'll be happy to check out a new build.
For me - and for my readers/viewers, or at least the ones who take my advice - there is no immediate problem. My boilerplate template contains my "real", fancier copyright notice. (the real symbol, a variable for the year, web contact address, etc.) Any photo that I actually develop, much less turn-in or publish, has that template applied. At ingest, I do add the original filename in the Transref. But that's only me.
Thanks!

P.S. for lurkers: Note that in order to "do any good", your copyright info needs to be in the IPTC fields. Google, for example, will never see it otherwise. Photo Mechanic will write it there for you if you put it in your template or if PM has read it from the Exif your camera writes. So long as you save or "OK" any metadata change in PM. But one way or the other, you should put your info in the IPTC fields. Don't depend on your camera.
